MySQL and related services still down

We’re still battling an issue we have yet to diagnose. At this point, we’re not expecting things to come back tonight. We’re working to move the services off the affected infrastructure to bring the critical services back. We’re getting outage pages into place for affected websites.

Once we’re through this, I’ll provide a detailed explanation of how things are set up and what went wrong for those who are interested in that. At the moment, we’re still struggling to figure out what exactly has gone wrong, since there’s no indication as to what’s causing the service failures.

Major outage affecting MCS systems

Our primary mysql database server is not allowing connections (or only sporadically allowing them), which is causing a number of services to fail including many websites. We’re working feverishly on getting it working again, but we have no ETA at this point since we’re still not able to get any real diagnostic info after multiple service and machine restarts.

More info as it comes available.

If you’re running MacOS 10.9 (Mavericks), please run software update to get the latest version (10.9.2). Aside from some bugfixes (including improved Exchange interopability), this contains a fix for a serious security issue with SSL certificate validation.

This update was just released, and should be available via the App Store/Software Update. It can also be found at Apple’s support downloads page here: http://support.apple.com/downloads/

Thank you.

Technical notes on the DayForce rollout

As you may have heard, the lab is switching to a new system for time tracking. More announcements on that will be coming from others as we get closer to the switchover date, including training information.

In order to use the new app, there’s a piece of software (Citrix Receiver) that you need to have installed. We’ve already installed it on all the Macs we manage. If you self-manage your machine, however, it’s easy to install. The simplest way is to visit https://appgateway.anl.gov with your browser. It will detect if you have the app and offer to install it if necessary. Right now, this URL is only accessible from inside Argonne — I’m looking into whether or not this is intentional as I was led to believe this was an “access anywhere” solution.

The software is available for Mac, Windows, Linux, Android, and iOS. (To install for Android or iOS, use the Google Play store or Apple App store and search for “Citrix Receiver”).

Documentation related to Dayforce can be found on Inside Argonne at http://inside.anl.gov/tools/applications/dayforce including links to login to the system. You won’t be able to login to Dayforce until the division has been switched to use it, but there’s an “Inside Argonne” app there you can test things out with.

Specific instructions on the Citrix software can be found at http://inside.anl.gov/tools/applications/citrix-gateway including instructions on installing in Windows, Mac OS, Debian-based systems, and RPM-based systems. If using a mobile client, after opening the Citrix Receiver software, point it at https://appgateway.anl.gov for app and login information.

Thanks!

Resource Calendars being migrated tomorrow (Friday, Feb 14th)

In a very confusing method of observing Valentine’s Day, some resource calendars are being migrated from the soon-to-be-retired Zimbra server tomorrow during the day. If you have any reservations or changes to make on these calendars, please get them in place today. Tomorrow during the day they will be moved to Exchange, and we’ll send out pointers to instructions on the new calendar location and procedures after the migration is complete.

The list of calendars being migrated are:

MCS Travel/Absence calendar
MCS Wireless Modem reservation calendars
MCS Projector reservation calendars
MCS Loaner Laptop reservation calendars

Thank you!

Adobe Flash Player update needed.

Please see the note below regarding a Flash Player update to address a vulnerability that is currently being exploited. For administrative users whose systems are managed by us, we’ll get you up to date. This notice is for all those who manage their own machines.

Thanks!

Adobe has released an Emergency Patch for Flash on all platforms on Feb 4.

http://helpx.adobe.com/security/products/flash-player/apsb14-04.html

Windows and Macintosh should update to Adobe Flash Player 12.0.0.44.

(Exploits ARE available and targetting MacOS machines too.)

Linux should update to Adobe Flash Player 11.2.202.336.

Google Chrome has Flash built in so needs to be updated the lastest patch level.

Internet Explorer Versions 10 and 11 also have built in Flash and have patches available.

There are currently exploits in the wild on this and appear to be picking up speed on distribution.

Please get updates installed on your systems as soon as possible.

We will be updating the DNS Blacklist, Web Proxy and Email gateway with signatures as bad stuff is found.  Be aware that things are changing faster than anyone can react to insert filters or blocks.

–Gene
